Some reports suggest there may be a third fatality but that is as yet unconfirmed.

A "commando" of people arrested or killed in a massive police raid in a Paris apartment were a terror unit capable of staging a fresh attack, the city prosecutor says.

"A new team of terrorists was neutralised and all indications are that given their arms, their organisational structure and their determination, the commando could have struck," said Paris prosecutor Francois Molins on Wednesday.
